Exam 2: Research Methodology

When a researcher who is collecting data does not know a study's hypothesis, the study is a:

When you pair two variables, and as one increases so does the other, your data will show:

A researcher that wants to get a sense of overall levels of electrical brain activity would use:

If a person wants to determine the average weight of customers in a store, she could create a questionnaire where customers check a category that indicates their weight, like 110 to 119 pounds, 120 to 129 pounds, and so forth. What statistic would be useful so she can include enough weight categories on her questionnaire?

Research that is done to test a theory:

When a researcher cannot manipulate variables in a project on the relationship between level of education and income, she will be forced to collect naturally occurring data. The data analysis would probably involve:

Researchers monitor changes in blood oxygen level when they record brain activity using:

Data collection is particularly problematic when a researcher uses participant observation because:

Which of the following would be best researched using a longitudinal study?

What approach have researchers used to document changes in glucose use in the brain during problem solving?

If a participant responds that she is getting a grade of A in a class but really is getting a B, she might not be lying; she might only remember her high test scores in that class. Such behaviour involves:

If a seriously brain-damaged patient cannot give informed consent to participate in medical research, researchers:

If the difference between two groups is statistically significant, it suggests that:

Researchers have discovered neurons in the brain that respond during emotional arousal. The best approach to studying these neurons is through:

A specific prediction of behaviour that is tested in an experiment is called a:

Laticia is studying the use of glucose in the brain to see how certain areas of the brain respond to a visual tracking task. Her research is likely to use:

The most powerful imaging technique, which documents changes in magnetic forces in the brain, is:

If a researcher finds that a participant produces very different scores on a task each time the participant engages in that task, a researcher can conclude that:

It would not be possible for a researcher to study creativity in an experiment if the researcher:

Paloma randomly assigns participants to two groups and compares the group that receives a treatment with the group that receives no treatment. The group that gets no treatment is the:
